Definitions
- the present invention relates generally to a fluid swivel coupling used for the purpose of interconnecting two fluid conduits and, more particularly, it relates to a fluid swivel coupling which permits relative rotational movement between the interconnected fluid conduits about two perpendicular axes.
- Swivel couplings are frequently utilized in connecting together fluid conduits where it is necessary or desirable to have one fluid conduit swivel or rotate about the interconnecting axis with respect to the other connected fluid conduit. Such couplings are especially useful in connecting a fluid conduit to a hand held device such as a paint spray gun where maneuverability is essential to the satisfactory operation of the spray gun.
- a swivel coupling may consist of a swivel body having a bore therethrough for accepting for rotational movement a spindle member which is engaged within the bore to prevent axial movement between the swivel body and the swivel member.
- a connecting means is provided at each end of this assembly so that fluid conduits can be connected to the swivel body and the spindle member with the result that the fluid conduits rotate about the axis connecting them.
- the above object, as well as others which will hereinafter become apparent, is accomplished in accordance with the present invention by providing a fluid swivel coupling which permits relative rotational movement between interconnected fluid conduits about two perpendicular axes.
- the fluid coupling includes a swivel body connectable to a fluid conduit, the swivel body having an axial bore therein, adapted to accept for rotational movement the spindle member of an assembly which includes a "U" shaped yoke whose arms rotatingly support a fluid conduit connector therebetween.
- the swivel coupling is provided with a fluid passageway between the interconnected fluid conduit which is continuous and remains uninterrupted throughout the range of movement of the swivel coupling.
- FIG. 1 is a side elevational view of a paint spray gun, partly broken away, showing the fluid swivel coupling of the present invention
- FIG. 2 is an enlarged cross-sectional view of the fluid swivel coupling of the present invention.
- FIG. 3 is a perspective view of the fluid swivel coupling of the present invention.
- FIG. 1 a hand held paint spray gun, generally designated 10, having a handle portion, designated 12, to which a fluid swivel coupling according to the present invention, generally designated 14, is connected.
- a fluid conduit such as the hose shown in phantom and designated 16, is connected to the end of swivel coupling 14 opposite the connection to handle portion 12 and serves to deliver liquid paint to spray gun 10.
- fluid swivel coupling 14 is basically comprised of four elements, a swivel housing, designated 18, a spindle assembly, designated 20, a fluid conduit connector, designated 22, and a fluid seal assembly, designated 24.
- Swivel housing 18 is provided with male screw threads, generally designated 26, for the purpose of threadably engaging swivel housing 18 with a suitable fluid conduit or within bore 28 of handle portion 12 (shown in phantom) of a spray gun. Wrench flats, designated 30 are provided on swivel housing 18 for the purpose of facilitating securement with handle portion 12.
- Axial bore 32 is provided in swivel housing 18 and is adapted to accept for rotational movement therein the spindle, designated 34, of spindle assembly 20.
- the surface of spindle 34 and the surface of bore 32 of swivel housing 18 are provided with complementary annular grooves which, when aligned as in FIG.
- Spindle assembly 20 further includes a substantially "U" shaped yoke, generally designated 44, extending from spindle 34.
- Yoke 44 is provided with parallel spaced apart arms, designated 46 and 48, interconnected by connecting link 50 to which spindle 34 is joined.
- Spindle 34 is preferably in the same plane as parallel arms 46 and 48 and preferably is centrally positioned on link 50 such that yoke 44 is balanced thereabout.
- Fluid conduit connector 22 is pivotally mounted for transverse rotational movement between arms 46 and 48 of yoke 44 by being mounted onto pivot pin 52 extending between arms 46 and 48.
- Pin 52 is formed of a hard, wear resistant material, such as tungsten carbide, ceramic, etc.
- the mounting surface of connector 22 is comprised of a bushing, generally designated 58, also formed of a hard, wear resistant material such as tungsten carbide, ceramic, etc., which is pres fitted into transverse bore 60 of connector 22.
- a bushing generally designated 58
- the clearance therebetween is preferably no greater than 0.0001 inches. However, it has been found that in the case of some heavy fluid materials the clearance may be as great as 0.001 inches.
- An uninterrupted continuous fluid pasageway is provided through swivel coupling 14 between its connection to spray gun 10 and its connection to fluid conduit 16.
- This fluid passageway is comprised of a series of bores and channels which maintain uninterrupted communication throughout the range of movement of swivel coupling 14.
- axial fluid bore 62 is provided in spindle 34 intersecting with transverse fluid bore 64 in link 50 of yoke 44, bore 64 in turn converges with axial fluid bore 66 in arm 48 of yoke 44.
- Bores 64 and 66 may be easily formed by drillings into link 50 and arm 48, respectively, and their origins may be capped by any suitable means, such as screws 68 and 70 as shown. As clearly seen in FIG.
- fluid conduit connector 22 includes a threaded nipple, designated 72, which extends from the mounting of connector 22 to yoke 44 and which is provided with an axial fluid bore 74 which passes through one side of bushing 58.
- the terminus of bore 74 coincides with an annular channel, designated 76, provided in pivot pin 52.
- Pin 52 is provided with an axial fluid bore, designated 78, which communicates with bore 66 in arm 48.
- Transverse bore 80 in pin 52 provides a connecting fluid passageway between channel 76 and bore 78.
- the end of swivel coupling 14 which is engaged with spray gun 10 is provided with a stem, designated 82, press into spindle 34 and extending into bore 28 of spray gun handle 12.
- Stem 82 is provided with a longitudinal bore therethrough, designated 84, which is axially aligned with bore 62 of spindle 34.
- Packing 24 surrounds stem 82 and establishes a fluid tight seal between bore 28 of spray gun handle 12 and swivel coupling 14 because of the compressive engagement of packing 24 between the end, designated 86, of swivel housing 18 and the shoulder, designated 88, in bore 28 of spray gun handle 12.
- This seal may be varied by threadably adjusting swivel housing 18 with respect to spray gun handle 12 thereby varying the compressive force acting upon packing 24 which, because of its resiliency, expands or contracts radially inwardly and outwardly.
- swivel 14 is constructed so that its moving parts revolve about two intersecting and perpendicular axes.
- the horizontal axis is designated the “X” axis and the vertical axis is designated the “Y” axis.
- the "Y” axis defines the axis of rotation of spindle 34 and hence of spindle assembly 20 as indicated by the direction arrow "A”.
- the positioning within spindle assembly 20 of pivot pin 52, about which fluid conduit connector 22 rotates, is such that is axis its aligned with that of horizontal axis "X”.
- the "X" axis defines the axis of rotation of fluid conduit connector 22 as indicated by the direction arrow "B".
